The Roman fort at Yotvata: a foundation under Valens?

The site was badly damaged in 1958, when a large trench for an oil pipeline was dug through the middle of it. Although Z. Meshel (Tel Aviv University) conducted soundings at the fort in 1975-76, the most important discovery was made accidentally in 1985, when a water pipe on the E side of the site burst, bringing to light a monumental Latin inscription.4 This stone block (not found in position but lying near the East Gate, from which perhaps it tumbled), refers to a Tetrarchic fort established by Priscus, praeses of Palaestina, who is also known from an inscription at Caesarea Maritima.5 Since that discovery, scholars have assumed that the fort at Yotvata was built when Diocletian transferred Legio X Fretensis from Jerusalem to Aila in the last decade of the 3rd c.6 Instead, we suggest that the fort was established no earlier than the mid-4th c., and most likely during the reign of Valens (364-78).
